Having had few episodes of af in past few weeks doc put me on 2.5mg bisoprolol. Then after another trip to ae upped it to 5mg. Unfortunately this made heart rate too slow and after a night in ae put back down to 2.5mg. Doc also wanted to put me back on amiodarone but because im waiting for a CRT-D to be fitted at another hospital decided not to. Its bit like a see-saw this problem of mine. But hopefully ill get sorted and like many others on site this weather not helping x
